Spearfish Torpedo
The Spearfish torpedo (formally Naval Staff Target 7525) is the heavy torpedo used by the submarines of the Royal Navy. It can be guided by wire or by autonomous active or passive sonar, and provides both anti-submarine warfare (ASW) and anti-surface warfare (ASuW) capability. Spearfish development began in the 1970s, with production starting in 1988, and deployment in 1992. By 2004, the new weapon had completely replaced the older Tigerfish torpedo. It is one of the most advanced torpedoes in the world. Design The torpedo is driven by a pump-jet coupled to a Hamilton Sundstrand 21TP04 gas turbine engine using Otto fuel II and hydroxyl ammonium perchlorate as oxidiser. The addition of an oxidiser improves the specific energy of the fuel by reducing the fuel-richness of the Otto fuel. The Spearfish, which are capable of travelling at , were designed to catch high-speed, deep-diving Soviet threats such as the . A microprocessor enables the torpedo to make autonomous tactical ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedoes Of The United Kingdom
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/ submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though ...

Cold War Weapons Of The United Kingdom
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

Varunastra (torpedo)
The Varunastra is an Indian advanced heavyweight anti-submarine torpedo, developed by Naval Science and Technological Laboratory (NSTL) of the Defence Research and Development Organisation (DRDO) for the Indian Navy. It is named after a legendary weapon created by the Hindu god of the oceans, Varuna. The ship launched variant of Varunastra torpedo was formally inducted in the Indian navy by defence minister Manohar Parrikar and security designed by security adviser satyam kumar on 26 June 2016. The minister in his speech said that the Government is in favour of exporting the torpedo to friendly nations including Vietnam. With some minor modifications the submarine variant of the torpedo is to be test fired shortly. Design This torpedo is powered by an electric propulsion system with multiple 250 KWs silver oxide zinc (AgOZn) batteries. It can achieve speeds in excess of , weighs around 1.5 tonnes and can carry of conventional warhead. This torpedo has more than 95 per cent in ...

DM2A4
DM2A4 Seehecht (export designation "''SeaHake mod 4''" ) is the latest heavyweight torpedo developed by Atlas Elektronik for the German Navy, as a further update of DM2 (Deutsches Modell 2) torpedo which was released in 1976. Description Being the successor of the DM2A3, it features an advanced electrical propulsion system and a fiber optic cable for torpedo guidance and communication, which, in conjunction with advanced signals processing and mission logic, makes the torpedo largely countermeasure resistant. The DM2A4/SeaHake mod 4 is the first torpedo ever to be guided by a fiber optic wire. With a fully digital system architecture, increased range and speed and its new conformal array sonar with a very wide panoramic sensor angle as well as the additional wake homing sensor, the DM2A4/SeaHake mod 4 provides greatly advanced performance over its predecessor. The homing head shell is a hydrodynamic optimised parabolic shape which aims to reduce torpedo self-noise and cavitation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mark 48 Torpedo
The Mark 48 and its improved Advanced Capability (ADCAP) variant are American heavyweight submarine-launched torpedoes. They were designed to sink deep-diving nuclear-powered submarines and high-performance surface ships. History The Mark 48 was initially developed as REsearch TORpedo Concept II (RETORC II), one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare. The Mk-48 torpedo was designed at the end of the 1960s to keep up with the advances in Soviet submarine technology. Operational since 1972, it replaced the Mk-37, Mk-14 and Mk-16 torpedoes as the principal weapon of U.S. Navy submarines. With the entry into service of the new Soviet in 1977, the decision was made to accelerate the ADCAP program, which would bring significant modifications to the torpedo. Tests were run to ensure that the weapon could keep up with the developments and the weapon was modified with improved acoustics and electronics. The new v ...

Insensitive Munition
Insensitive munitions are munitions that are designed to withstand stimuli representative of severe but credible accidents. The current range of stimuli are shock (from bullets, fragments and shaped charge jets), heat (from fires or adjacent thermal events) and adjacent detonating munitions. A munition can have its vulnerability reduced by a number of means used on their own or in combination such as a reduced vulnerability energetic material, design features, additions or changes to packaging etc. The munition must still retain its terminal effect and performance within acceptable parameters. Description Insensitive munitions (IM) will only burn (rather than explode) when subjected to fast or slow heating, bullets, shrapnel, shaped charges or the detonation of another nearby munition. The term refers to warheads, bombs, and rocket motors, although different countries' armed forces may have their own definitions. Due to "accidents, and the subsequent loss of human life, cost o ...

Beith
Beith is a small town in the Garnock Valley, North Ayrshire, Scotland approximately south-west of Glasgow. The town is situated on the crest of a hill and was known originally as the "''Hill o' Beith''" (hill of the birches) after its ''Court Hill''. History Name Beith's name is thought to emanate from Ogham, which is sometimes referred to as the "''Celtic Tree Alphabet''", ascribing names of trees to individual letters. ''Beithe'' in Old Irish means ''Birch-tree'' (cognate to Latin ''betula''). There is reason to believe that the whole of the district was covered with woods. The town of Beith itself was once known as 'Hill of Beith' as this was the name of the feudal barony and was itself derived from the Court Hill near Hill of Beith Castle. Alternatively, Beith may be derived from Cumbric ''*baɣeδ'', 'boar' (Welsh ''baedd''). The local pronunciation of the name would favour this theory. The Wood of Beit, now the 'Moor of Beith', has been identified as an Arthurian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
